摘要
盱眙地区是我国重要的凹凸棒石粘土矿产地,对其成矿条件的分析有助于揭示该区凹凸棒石粘土矿的成因。本文对盱眙地区凹凸棒石粘土矿的成矿条件进行分析和总结,认为新近系玄武岩的多次喷发沉积为成矿提供了优良的成矿空间和物质来源。凹凸棒石矿化与区内接受陆源沉积同期,成矿时代大致在10.32~16.52Ma;区内独特的沉积环境为凹凸棒石粘土矿成矿提供了有利条件。
The Xuyi area is the most important attapulgite clay producing area in China,and the analysis of the metallogenic conditions of the attapulgite clay deposit helps to reveal the genesis of the attapulgite clay deposit in this area.In this paper,the oreforming conditions of attapulgite clay ore in Xuyi area are analyzed and summarized.It is concluded that the eruption and deposition of Neogene basalt have provided excellent ore-forming space and material source for ore formation.Attapulgite mineralization and subsidence in the area were in the same period of continental source deposition,and it was speculated that the mineralization period was roughly between 10.32 and 16.52Ma.The unique sedimentary environment has provided favorable conditions for attapulgite mineralization in Xuyi.
